early game, I bet low, then if I get a few wins, I will increase my bet to the maximum. that's how I play.
I prefer to be part of the area in gambling that I have experience in and that I have been playing regularly. I love the sports thing in this regard because it is very easy to pick a team you find good enough and bet on. The gambling in sports is not a certain thing either but if you understand how things work, you would make it till the end. I have seen friends making and loosing money in sports gambling but the average money you win is more than that you lose.
